I`m using pioneer A04 and software Nero 5.5, trying to put spider-man svcd onto dvd-r using the drag& drop.spider-man is on 3 discs. I inserted the first disc into Liteon dvdx16, dragged the files over and dropped them over to the left hand side, went in no problem. When I inserted the second disc I was asked did I want to replace the existing files, I answered no. How do you add the 3 discs to copy onto dvd-r?. I`m new to this. Would someone please help.....
